Suburban Square Restaurant History At 105 Coulter

This spot on the square at 105 Coulter Avenue has been home to a number of (mostly) long-running restaurants over the last 30 years. It’s not completely clear when this location was constructed and what the original use was for the domed octagonal space that juts out from the front. In the mid-1980s it was Eden Restaurant, a trendy cafeteria-style concept launched by Steven Poses, … Continue reading Suburban Square Restaurant History At 105 Coulter

Ardmore Macy’s Closing And Renovation

The Ardmore Macy’s closed its doors for good on Sunday, March 20th 2016 after almost 86 years of continuous operation.

Update: RisingHF Gateway RHF0M301 with Loriot Community Network

It’s been about a year since I posted an unofficial manual for getting the Seeed Studio 915 MHz RisingHF Raspberry Pi gateway up and running with Loriot. In that time, I had hoped that there would be more resources available for enthusiasts to find information about setting up gateways, nodes and sensors. However, it looks like complete and reliable information is still hard to come … Continue reading Update: RisingHF Gateway RHF0M301 with Loriot Community Network

Ardmore, PA Radio Shack Closed

My local Radio Shack closed on June 27, 2017 after 50 years in operation. This was my go to place for electronic parts and occasional electronics since 1988 and it will be greatly missed. Originally the store was listed as one that would remain open, but it was not to be. In addition to the store’s longevity, some of the staff had been there for … Continue reading Ardmore, PA Radio Shack Closed

Sniffing GSM with SDR

I’ve been fascinated by software defined radio (SDR) for years but investigating the GSM cellular network has always been just a little too challenging and slightly out of reach. All of that changed earlier this year when someone finally posted a workable, step-by-step guide for decoding (but not decrypting) cellular (GSM) radio traffic. For those not familiar, SDR involves moving much of the functionality of … Continue reading Sniffing GSM with SDR

Pushing a bt.tn button

The Internet Button

While perusing the various channels on IFTTT recently, I came across one for something called “bt.tn.” My curiosity led me to a Finnish site that sells a very interesting product: a large pushbutton that can control anything that is connected to the internet. The bt.tn comes in various colors and has both Wi-Fi and cellular models. The operation from a user’s perspective could not be simpler. You … Continue reading The Internet Button
